BLDC Motor Controller for 24VDC Mini Compressor

[mechdude]

I’m a mechanical engineer and I am looking for a motor controller for my 24VDC, **HA27CRDC24 **LingYue mini compressor. The controller it comes with makes it extremely difficult to operate the compressor at maximum RPM. My understanding is that it uses a brushless DC motor to operate. Is there something anyone can recommend for me to buy? I considered replacing the trimpot on the circuit board for another but I’m not entirely sure how to do this while achieving the RPMs that I want.

Thank you for the help!

Hi,

We don’t see how replacing the trimpot on the actual controller will fix your RPM issue.
You can try to change the DC motor controller. Here is a Motor Controller that could be a good fit for your compressor.
However, this motor controller has only a PWM input (no analog input). Therefore, you will need a microcontroller to interface with, like an Arduino UNO board with a potentiometer input (on the Arduino) to vary the speed of the DC motor.
Or, you can use an Analog voltage DC controller as this one with a potentiometer input.

Cheers,
